0、创建操作系统用户
扩容节点执行。
[root@czg0 package]# groupadd foundationdb -g 2002
[root@czg0 package]# useradd foundationdb -g 2002 -u 20021、安装路径创建
扩容节点执行。
[root@czg2 /]# su - foundationdb
[foundationdb@czg0 ~]$ mkdir -p /opt/GCDW/FoundationdDb
[foundationdb@czg0 ~]$ cd /opt/GCDW/FoundationdDb/
[foundationdb@czg0 FoundationdDb]$ mkdir Log

[foundationdb@czg0 FoundationdDb]$ pwd
/opt/GCDW/FoundationdDb 2、foundationdb.conf配置
扩容节点执行。
[foundationdb@czg0 Config]$ pwd
/opt/GCDW/FoundationdDb/Config
[foundationdb@czg0 Config]$ cat foundationdb.conf
[fdbmonitor]
user = foundationdb
[general]
cluster-file = /opt/GCDW/FoundationdDb/Config/fdb.cluster
restart-delay = 60
[fdbserver]
command = /opt/GCDW/FoundationdDb/Bin/fdbserver
datadir = /opt/GCDW/FoundationdDb/Data/$ID
logdir = /opt/GCDW/FoundationdDb/Log/
public-address = auto:$ID
listen-address = public
[fdbserver.4500]
class=stateless
[fdbserver.4501]
class=transaction
[fdbserver.4502]
class=storage
[fdbserver.4503]
class=stateless3、fdb.cluster配置
扩容节点执行。
格式：
Description:Id@Ip:Port,Ip:Port,...| 名称 | 描述 |
| Description | 描述信息，包含数字和字母以及下划线。 |
| Id | 集群ID，包含字母数字字符（A-Z、a-z、0-9）的任意值。 |
| Ip | 地址。 |
| Port | 端口。 |
配置：
[foundationdb@czg0 Config]$ pwd
/opt/GCDW/FoundationdDb/Config
[foundationdb@czg0 Config]$ cat fdb.cluster
MyFdb:Sun@192.168.142.11:45004、修改权限
扩容节点执行。
[root@czg0 FoundationdDb]# chown -R foundationdb:foundationdb /opt/GCDW/FoundationdDb
[root@czg0 FoundationdDb]# chmod -R 755 /opt/GCDW/FoundationdDb5、拷贝文件
[foundationdb@czg0 ~]$ scp -r /opt/GCDW/FoundationdDb/Bin/* foundationdb@czg1:/opt/GCDW/FoundationdDb/Bin/
foundationdb@czg1's password:
fdbbackup 100% 26MB 2.1MB/s 00:12

fdbmonitor 100% 790KB 1.1MB/s 00:00
fdbserver 100% 92MB 1.4MB/s 01:07 6、systemd服务配置
扩容节点执行。
[root@czg0 Release]# cat /etc/systemd/system/Foundationdb.service
[Unit]
Description=FoundationDB (KV storage for cnch metastore)
[Service]
User=foundationdb
Group=foundationdb
Restart=always

[Install]
WantedBy=multi-user.target7、system重载配置文件
扩容节点执行。
[root@czg0 Release]# systemctl daemon-reload8、启动服务并开机自启
扩容节点执行。
[root@czg0 Release]# systemctl enable Foundationdb.service
Created symlink from /etc/systemd/system/multi-user.target.wants/Foundationdb.service to /etc/systemd/system/Foundationdb.service.
[root@czg0 Release]# systemctl start Foundationdb.service9、添加节点
原调度节点其中一个执行即可
fdb> coordinators 192.168.142.10:4500 192.168.142.12:4500 192.168.142.11:4500
Coordination state changed10、拷贝fdb.cluster配置文件
上面执行命令的调度节点，将配置文件拷贝到其他节点。
[gbase@czg0 ~]$ scp /opt/GCDW/FoundationdDb/Config/fdb.cluster foundationdb@czg1:/opt/GCDW/FoundationdDb/Config/
foundationdb@czg1's password:
fdb.cluster 100% 176 156.0KB/s 00:00
[gbase@czg0 ~]$ scp /opt/GCDW/FoundationdDb/Config/fdb.cluster foundationdb@czg2:/opt/GCDW/FoundationdDb/Config/
foundationdb@czg2's password:
fdb.cluster 100% 176 240.6KB/s 00:00 11、重启服务
所有节点执行。
[root@czg0 ~]# systemctl restart Foundationdb.service12、验证
为了方便，所以/etc/foundationdb/fdb.cluster也拷贝了一份。
[foundationdb@czg0 ~]$ fdbcli
